y ... Do you know of any automation tools that can examine shell scripts and list utilised commands and programs to make the analysis easier? There are about 25 scripts doing various functions mainly file system commands such as copying files, sed, invoking sqlplus, grep etc.....
I posted a perl script that may help you see what commands might be used in shell scripts. It is rough because it is an experiment. There is an example input shell script with the resulting output. The perl script, p1.txt, should be copied to a file p1, add execution permission, then run it as shown in the example.
The perl script ran correctly in this environment:
I wrote a script in ksh93 (the OS is AIX 5.2, ML7), which failed to run. After some testing i found out why, but the answer is a bit dissatisfying. Look for yourself:
#!/bin/ksh93
# --------- Step Names
typeset achStepName="foo"
typeset achStepName="bar"
typeset achStepName="fubar"... (3 Replies)
Any means of running ksh93 in a ksh88-mode?
Might sound odd, but I want/need to restrict U/Win-developed scripts to correspond to the ksh88 version on my Solaris environment(s). Thanks. (2 Replies)
Hi,
I have a script that calls an external program to perform some calculations and then I read with "grep" and "sed" values from the output files. I've noticed that performance of KSH93 degrades with every iteration. The output files are all the same size, so I don't understand why after the... (2 Replies)
Hi ,
I am working on Linux, with ksh93 installed.
The following statement
echo \\n
just prints
\n on this shell.
However on pdksh
echo \\n gives a blank new line as a output.
What is the correct way of printing a new line character on the ksh93? (4 Replies)
This problem seems to be specific to ksh93.
If you run with set -x some scripts don't work properly. For example:
$ cat ksh.test2
] && print FUBAR! || print OK!
$
$ /bin/ksh93 ksh.test2
OK!
$ /bin/ksh93 -x ksh.test2
+ ]
+ print FUBAR!
FUBAR!

Trying to find out why this is... (8 Replies)
Hello everyone,
I am trying to embed some tcl code inside a ksh93 script but I am not having any success.
I even tried the simplest of code, something like this:
.
.
jk=$(echo $(tcl << |
write_file junkme "test"'
|
))
just to see if a file gets written. When I run there are no errors, but ... (3 Replies)
My OS is Linux (kernel 4.08.something) and AIX (7100-04-01-1543), the used ksh versions are:
ksh88: Version M-11/16/88f (AIX)
ksh93: Version M 93t+ 2009-05-01 (AIX), Version M 93u (Linux)
When writing a parser for stanza files in ksh i encountered a rather strange behavior. Here is a... (4 Replies)
Hi everyone !
Im trying to know from wich version of AIX KSH93 is available ?
Internet tell me 6.x and 7.x AIX are available, bue what about 5.x ?
Is KSH93 available on AIX 5.x ?
Is it the same way to manipulate variables as KSH93 on 7.x ?
Thanks for your support and have a nice day ! (2 Replies)

alien::package::rpm
Alien::Package::Rpm(3pm) User Contributed Perl Documentation Alien::Package::Rpm(3pm)NAME
Alien::Package::Rpm - an object that represents a rpm package
DESCRIPTION
This is an object class that represents a rpm package. It is derived from Alien::Package.
FIELDS
prefixes
Relocatable rpm packages have a prefixes field.
METHODS
checkfile
Detect rpm files by their extention.
install
Install a rpm. If RPMINSTALLOPT is set in the environement, the options in it are passed to rpm on its command line.
scan
Implement the scan method to read a rpm file.
unpack
Implement the unpack method to unpack a rpm file. This is a little nasty because it has to handle relocatable rpms and has to do a bit
of permissions fixing as well.
prep
Prepare for package building by generating the spec file.
cleantree
Delete the spec file.
build
Build a rpm. If RPMBUILDOPT is set in the environement, the options in it are passed to rpm on its command line.
An optional parameter, if passed, can be used to specify the program to use to build the rpm. It defaults to rpmbuild.
version
Set/get version.
When retreiving the version, remove any dashes in it.
postinst
postrm
preinst
prerm
Set/get script fields.
When retrieving a value, we have to do some truely sick mangling. Since debian/slackware scripts can be anything -- perl programs or
binary files -- and rpm is limited to only shell scripts, we need to encode the files and add a scrap of shell script to make it
unextract and run on the fly.
When setting a value, we do some mangling too. Rpm maintainer scripts are typically shell scripts, but often lack the leading shebang
line. This can confuse dpkg, so add the shebang if it looks like there is no shebang magic already in place.
Additionally, it's not uncommon for rpm maintainer scripts to contain bashisms, which can be triggered when they are ran on systems
where /bin/sh is not bash. To work around this, the shebang line of the scripts is changed to use bash.
Also, if the rpm is relocatable, the script could refer to RPM_INSTALL_PREFIX, which is set by rpm at run time. Deal with this by
adding code to the script to set RPM_INSTALL_PREFIX.
arch
Set/get arch field. When the arch field is set, some sanitizing is done first to convert it to the debian format used internally. When
it's retreived it's converted back to rpm form from the internal form.
